ELECTRIC BATTERY.

Application filed August ll, 1902.

To all whom it may; com-tu n:

Be it known that l. iYltLmn i.it itiISQN, a citizen of the United States oi .inierica, and resident of (hit-ago, Cook countv, lllinois, have invented a certain new and hsel'ul linprovclncnt in Electric Batim'ies, of which the following is a specilicat ion.

My present invention relat s to an improved containing ccl lKz-r an electric bat tor) in which broiniu is used. it is nlwessarv t provide a containing: cell oi sit-ll a chaiznter of material as will resist the attacks o! the bromin and also it; is desirable to provide a cell the bottom o'l' which also constitutes the negativeclement.

in carrying out; my invention 1 provid containing cell c a of carbon. and this material not only is capable of resisting the attacks of the bromin but it all provides a material suitable for the negat e element of the battcry.

l have described and claimed in another application of even date herewith, No. 119,205, and hereinafter referred to, a bromin gravity cell in which the bromin. is depositcd or placed upon the bottom of the cell. It is more particularly to such a battcrythat my present invention is adapted. In that application 1 have stated that the bromin is deposited or placed upon the bottom of the cell and have defined what is meant by this expression. in this application I shall show, describe, and claim an electric battery using broniin in which the bot tom of the cell is the negative clement itself.

Reference may now be had. to the accompanying drawings in which: Figure l, is a perspective view of a containing cell with all of the parts removed from its interior and showing the bottom of the cell as the negative element. Fig. 2, is a cross section on the line lli -Lb' of Fig. 1. Fig. 3 is a perspective of the completed battery. Fig. 4 shows a number of the batteries connected and arranged in a tray. Fig. 5 is a plan oi the ar angcment shown in Fig. 4-.

In an applicatiem for patent tiled concur-- rently herewith No. 1 19,205, i have described and claimed, as generally stated, a gravity bromin cell and i will not here repeat the description.

It is well known that broniin attacks and destroys nearly all of the metals, and it necessary to provide a material for t 1c cell which will withstand uch. attacks. .l have Specification of Letters Patent.

Serial No. 119,202.

found that carbon is an excellent material for the purpose on account of its cheapness and because it is but little allccted by the bromin. i rial for the negative clement and by rnakin the whole cell of carbon a bottom A for sai cell is provided. the negative element the pockets (L are l'ornicd, the purpose of which I have set forth in said application to be to maintain the liquid bromin more stable in the bodily movements of the cell. i

Above the negative element A is the p0Si-' live element 8 or copper wire gauze or other suitable nuttcrial. The bromin is placed upon, or clectro deposited u )on the carbon bottom A of the carbon cell, and when so placed is upon the negative element and within the. pockets.

it is desirable that the carbon should be as ure as possible and of great density. The cells may be treated with a suitable material to render them im )ervious to lir uids, and they may then be placed in a suita le tray C and cemented therein by a suitable sub-- stance which will not be attacked by the bromin. substance which is not attacked by the bromin may be used and the connections made as shown in Figs. 4 and 5.

It. is known that bromin will attack and destroy many materials and many materials which it does not materially allect are destroyed by the bromin under the electrical charge but even under the charge the bromin affects the carbon but little. I

As carbon is a conductor it is evident that metallic upon the exterior of the cc AS shown, the battery may have a cover or lid Dadapted to rest upon the space or distance pieces (I, which latter in turn rest upon the positive element. An insulating frame F is fitted within the cell, and is provided with a ledge f which supports the positive element. The

cell or lmgativc element is provided with a The ositivc element is connected with a binding-post G through the me dium of a conductor g. A vent II of any suitable known or approved character can also be. provided.

The serial numbers ol my co-pending applications are as follows: 1 119,204, and 119,205.

it will be understoodthat the positive ele- The carbon cell and a suitable soft,

Carbon is also an excellent matein this bottom A, which is I connections ma be established is utilized, e

rial.

What I claim as my invention is:

1. In an electric battery in which bromin cell having a carbon bottom serving as the negative element the battery being so constructed that the deposit of bromin is held by grevit upon the upper surface of the bottom of t 1e cell, said upper surface being the negative element.

2. In an electric battery in which broinin l is -utilized, at carbon cell the battery being so constructed that the deposit of bl' Ollllll is held by gravity upon the upper surface of the merit B can be made of any suitable metebottom of the cell, said upper surface being the negetiveeleinent.

3. A bromin storage battery having a cell constituting the negative element the bettery being so constructed that the deposit of broniin is held. by gravity upon the upper surface of the bottom of the cell, said upper surface being the negative element.

Signed by me at Chicago, Cook county, Illinois, this 8th day of August 1902.
